Advantages

Continuous Duty

Arrow engines are designed for continuous duty 24 hours a day, day after day. Dependable performance when you need it. Arrow's heavy duty design features a heavy flywheel, a governor speed control, and a pressurized full flow lubrication system to assure continuous operation.

Oilfield Tough

Over 75,000 Arrow engines are powering pumping jacks in oilfields from the frozen tundra's of Canada, to the mountains of South America; from the deserts of the Middle East, to the jungles of Indonesia. Many of the original engines built in the 1940's are still running today. Tough means they work harder, longer.

Gas Fueled

Arrow engines run on a variety of low BTU gases; natural gas, wellhead gas, methane, butane or propane. Whether in remote jungles or in civilization, locally available gas fuel frequently costs much less than bringing in liquid fuel or electric power. The single cylinder Arrow engines can also be equipped with a fuel lift pump and will operate on gasoline.

Economical Operation

Studies performed in the U.S. have shown that operating costs for Arrow engines can be as low as half the cost for equivalent HP electric motors. Since every area is different, you owe it to yourself to compare the costs in your area.

Easy Maintenance

Arrow engines are designed for easy, quick field maintenance. The oil level can be checked and adjusted while the engine is running. Easy access enables replacing piston rings and wet cylinder sleeves* in the field; and Arrow parts are interchangeable from the first model made. Ignition-Starfire Solid State Ignition Systems are standard for Single Cylinder engines and optional on Twin Cylinder engines. Also available as options are high tension or solid state magnetos, or Altronic ignition systems.

Arrow “Engineered” Improvements

Improvements to the Heavy-Duty C-Series Engines since May 1977 (most all are retrofitable to earlier models using current kits):

Heavy steel fabricated sub-base

Full flow oil system with spin-on filter

A mounting pin for Arrow 990

Portable starter added to sub-base

Bronze crankshaft gears for C-46 through C-106

Arrow oil filler added to engine (ASP-1)

O-ring modified rocker shaft plugs

Reliable stainless steel braided oil lines

Ball rod ends standard on all Arrow engine models

Stainless steel water filler added as standard (ASP-3A)

Vibration-free cross braced radiator shells

Common muffler made standard on C-Series engines

Lifting eyes added to facilitate engine handling

Newly increased engine horsepower with the change to Impco 100 and 200 carburetors

All Arrow Engines are either electric 12-volt ring gear starting or blow down air-gas starting systems

Our A-Series line of multi-cylinder engines can accommodate a variety of applications, both common and unusual. A-Series engines are available in turbo and cross-flow configured intake and exhaust manifolds. These precision engineered and time-tested engines are as dependable as they are versatile. The RPM runs between 900 and 1,800, with HP from 17.5-109.

Power Units

These engine can also be packaged as power units with everything your needs require. They are perfect for rotational pumping units, hydraulic pumping units, hydraulic skids for PC pumps or for any form of artificial life where power is needed.

All ratings corrected to 500' (152m) altitude, 29.38" (746mm) Hg. and temperature of 85°F (29°C). Natural gas ratings are based on use of 900 BTU (33.5 J/cm³) LHV gas. HD-5 propane ratings are based on use of 2335 BTU.
